High anxiety this evening after someone knocked on back door and said "sorry, wrong house". On high alert, I was watching street & spotted someone walking down the middle. Same person, only this time he had a sock hat on. I asked if he found right house & he walks to porch to tell me he lost his phone battery....which was a lie because I could see phone display was lit! I told him not to come back to this house. Waited for neighbor to get home & told him so his wife & daughter would be alert. Fortunately, there's a lot of dogs in the neighborhood! I'm getting porch light repaired tomorrow for the back entrance we use to come & go!
